When '029ab30b4c0a ("powerpc/mm: Enable radix GTSE only if supported.")'
made GTSE an MMU feature, it was enabled by default in
powerpc-cpu-features but was missed in pa-features. This causes random
memory corruption during boot of PowerNV kernels where
CONFIG_PPC_DT_CPU_FTRS isn't enabled.
Fixes: 029ab30b4c0a ("powerpc/mm: Enable radix GTSE only if supported.")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
